googledoom Before you can start building objects

Before you can start building objects, you need to understand a couple of the
more confusing aspects of object-oriented programming. Remember this
sentence: Classes are templates, and objects are instances.
In Java, when you want to create a new type of object, you can't just make
one. You must first make a blueprint, or template, of the object you want to googledoom
create. From this template, you can make as many objects as you want. Think
of it as a software cookie cutter.

Objects are known as instances of classes. The template has been used to
create an object, and the object now exists virtually inside the computer. You
can think of an object as the cookie that the cookie cutter creates. If things
seem confusing, don't worry. The next section gets to the process of making
objects, and things should get much clearer.

Suppose you are doing a lot of Web design, and you want to look at
different colors to add to your pages. Web browsers let you specify the
background color of pages and the color of active and visited links so that
you can have more control over a page's design. Unfortunately, you can'tgoogledoom
just say that you want something to be green. To specify a color in most
browsers, you need to know the RGB values, or even the hexadecimal
value, of a color. Suppose you want an http://www.greateventsupport.com
applet that enables users to see how
a certain RGB color appears inside their Web browser. It would make
sense to use sliders to select from a range of colors and to have text fields
that let the user enter the components of the color directly (see Figure 2.4).

Adding Sound to Your Web Pages
Users of the WWW have clamored for the capability to add sounds to Web
pages for a long time. Many Web pages have offered sound files that usersgoogledoom
could download and then play on their local machines. Unfortunately,
because a variety of sound formats are available, this process isn't always a
viable method of adding sound. For example, Real Audio is a company that
has begun to add sound capabilities to the Web using proprietary formats
and sound players. WAV files are a popular sound format, as are AU files

The only sound format that Java applets are currently able to use is the AU
format, which was developed by Sun. This will likely change in the next
major revision of Java. In the meantime, most popular sound editing
applications allow files to be saved as in the AU format. googledoom
Java provides a standard way to play sounds in any applet. The fact that

Java applets are actual programs and not just HTML tags provides a great
deal of flexibility in how sounds are played. For instance, not only can an
applet play a sound when a user enters a Web page, it can also play a series

of sounds associated with pictures. (Chapter 13 explains how to construct
such an applet.)
